METHOD OF TREATING OIL-SOAKED WASTE.

Specification of Letters Patent. Patented Jan, 21,1913.

Application filed September 14, 1912. Serial No. 720,330.

To all whom it may concern:

Be it known that I, ISAAC J oNEs, a citizen of the United States,residing at Cheyenne in the county of Laramie and State 0 WVyoming, haveinvented certain new and useful Improvements in Methods of TreatingOil-Soaked Waste; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to the method of renovatingoil soaked waste,such'as is used in journal boxes and like bearings, and has for itsobject to treat the waste in such manner as to completely remove thedirt from the waste, to remove the short pieces of yarn, dissipate andremove the glazed surface which ordinarily forms upon the waste next tothe journal, to fluff the fiber in the yarn, and to efi'ect theseseveral results without materially diminishing the oily or greasycontent of the waste, so that the thoroughly cleaned oil soaked wastemay be further employed without the necessity of-satu'rating the samewith a new portion of oil or grease.

To this end, the invention relates to the method of cleaning dirt andthe like from oil impregnated waste without materially diminishing theoily content, which consists in agitating subjecting the body ofagitated waste to blasts of heated fluid medium, preferably steam, Whichblasts traverse the waste in all directions forcing the dirt and foreignmaterial out of the body-of the waste, expanding or fiufiing theindividual fibers of the wastea'nd at the same time leaving the oilycontent practically intact in the body of the waste.

A relatively simple form of apparatus for carrying out the process isillustrated in drawings, in which is a side elevation of the said Fig. 2is a vertical longitudinal Fig. '3 is a vertical Figure 1 apparatus;section therethrough;

' transverse section; Fig. tis a perspective 1 a hood or cover 3 ofsimilar shape,

cover-is hinged at 4 to the frame 1 and is frame of wood or view of thespraying head employed inthe apparatus. I

Referring to the drawings, 1 indicates :a

2, semi-cylindrical in shape, above which is the waste andsimultaneouslyother suitable" material in which is secureda-pan-like-receptacle which tion by a screw and thumb nut 5. The lowerpart of the portion of the receptacle 2 is provided with a dischargeoutlet 6 emptying into a suitable drip pan 7 Inclosed in the casingformed by the parts 2 and 3 and journaled in suitable bearings 8 carriedby the frame 1, is a foraminous drum, preferably composed of an outercovering of wire mesh 10, attached to solid headsor end portions 11,which'latter are secured to the T-couplings 14, which in turn areprovided with trunnions 12 engaging the bearings 8 aforesaid. The righthand trunnion 12 is formed by a supply pipe for steam or other fluidunder pressure, which is connected by a suitable swiveling coupling 16to the supply pipe 17 Connected to the T-couplings 14 and disposed as arectangular frame within the rotary drum is a spray pipe 13 havingperforations 15 which direct jets of the fluid medium radially, towardthe axis of the drum and longitudinally or parallel with the drum axis.The left hand trunnion 12 is provided with a crank or other suitablemeans for rotating the drum and the spray pipe contained therein. Oneside of the said drum is provided with a hinged door 10 adapted to admitthe waste to and discharge the same from the drum. If it is desired torotate the drum automatically, steam or other fluid medium underpressure is supplied in jets which strike the peripheral surface of thedrum at a suitable angle by means of a spray pipe 21 connected with thesupply pipe 20, which latter, like the supply pipe 17 is provided withthe usual form of shut-oif valve.

In operating the ap aratus journal boxes and the like-is thrown into thecylinderlthrough the hinged door in the side of the drum after which thedoor 10 'is closed and the hood-like member of the ca sto carryout thenovel method, the 011 soaked waste from jets from the thoroughlypermeate the same and as a consequence the dirt and short pieces ofwaste I 1 let 6 into'the drip.trough 7. The s aking L or agitation ofthe waste, together with the impingement of the steam jets upon theagitated waste also subserves the purpose of breaking up the glaze whichis commonly formed on the surface of the waste adjacent the journalswhich is apparently due to a mixture of dirt and oil, which prevents.the oil passing through the waste to the journal and is a very commoncause of overheating in the journals. It has been the common practiceheretofore to attempt to remove this glaze and other foreign matter fromold waste by shaking it up by hand which,,however, has merely the effectof distributing the glazed portion of the waste throughout thewhole-mass without removing the glaze. By the present method, however,the glaze is not only fractured and broken away from the waste, but alsoso far broken up and dissipated as to admit of its being shaken out ofthe waste and carried off with the other foreign material. A stillfurther result of the process aforesaid is the swelling or flufling ofthe fiber in the'yarn constitut- 7 ing the waste which isobviously adesirable feature and one which 'is not attained by any ofthe ordinarymethods of cleaning orv renovating waste.

One of the most important results of the. process aforesaid is that,while 1t removes I like from 'oil impregnated waste without all dirt andother deleterious material from the waste, it does not extract the oil,but leaves the oily or greasy content of the waste, unimpaired andpractically intact, distributed throughout the body thereof.- In all ofthe waste'cleaning processes heretofore employed, it has been the commonpractice to remove or wash out the oil so.

that when the cleaned waste was againused 1t was necessary to completelyimpregnate tle entire mass of waste with a fresh supply 0 oil.

lubricantcontained in the waste is carried off during the cleaning ofthe waste by the process herelnbefore descrlbed. To illustrate' by aconcrete example, it requires approximately four pounds of lubricatingoil to saturate. one pound of new waste or old waste washedor renovatedby the .former .procesis;v In a series of operations, involving Thepresent invention results in a. great saving of 011 in thatvery littleof the improved process aforesaid. 1

In carrying out the process, it is desirable that the steam or otherfluid medium be of a suflicient temperature tocausethe oilto. becomesoftened without rendering it so highly fluid as to run' out of thewaste and the pressure of the fluid medium should/be sufficient to causethe jets traversingthe waste to blow the .dirtand foreign. material outof the waste andpermit the same'to escape through the foraminous wallsofthe rotary "drum. Very satisfactory. results have been obtained in anapparatus such as illustrated in the drawings, with substantially drysteam at about eighty pounds pressure supplied to a body of waste. inthe drum for approximately three. minutes, the

result being a thoroughlycleaned and. flulfed waste, ready for reuse andwith its oily content practically unimpaired. i Y What I claim as myinvention is 1. The method ofclean'ing dirt and the like from oilimpregnated Waste without, materially diminishing the. oily content,which consists in. agitating the waste and simultaneously subj eatingthe same to blasts of heated fluid medium. 7

2. The method of cleaning .dirt and the materially diminishing the oilycontent, which consists in agitating the waste and simultaneouslysubjecting the same to blasts of steam. v

3. The method of cleaning dirt and the like from oil impregnated wastewithout materially diminishing the oily content,

which consists in tumbling the waste in the presence of blasts of'steamwhich traverse the materiaL- g I 4. The method of cleaning dirt and thelike from oil impregnated waste without materially diminlshing the oilycontent, which consists in separating and loosening the waste byagitation and subjecting the separated and loosened waste to blasts ofheated fluid .medium.
